Abstract
The utility model brings on an enclosed stop valve for split air conditioner, comprising a connection tube, a valve body, a valve handle, a small sealing cap, a valve inside, a sealing seat, a sealing ring, a gland stud, a big sealing cap and a check nut. The utility model is characterized in that a sealing assistance formed by the sealing seat, the sealing ring and the gland stud is in cuneate structure; the lower end of the valve handle is the shape of single conical surface with circular arc, and the big sealing cap is hexagonally prismatic; in addition, to the characters, the valve base and the lower part of the valve body of the other structure are welded; the valve handle 15 is provided with the download-type structure, and the C-end axial lead and the B-end axial lead of the valve are not in the same straight line. The utility model has the characteristics of reasonable sealing action, good effect, safe and reliable use, convenient operation and no-leakage state, etc.
Description
The utility model proposes the closed stop valve of a kind of split-type air conditioner device.
Prior art, as the patent No. 92227471.1, its valve rod head is a biconical surface structure, yet the conical surface under being that works, before stem movement arrived the limes superiors position, existing refrigerant entered between the soft seal position of the last conical surface and valve rod, and this part refrigerant is easy leakage.Big sealing cap has only when being screwed off, and just may realize the debugging and the maintenance of air conditioner, and like this, the sealing that coincide of the outer omoplate of the inner conical surface of its head and valve body just loses its effect.Therefore, the soft seal in fact for once of this valve, but not a hard sealing of secondary and a soft seal.Secondly, by the sealing pair that sealing seat, seal ring, gland double-screw bolt are formed, it is shaped as rectangular-shaped, this shape and structure, and it requires longitudinal force very big, just can play sealing effect, renews in case the sealing seat distortion certainly will be submitted an expense account.Once more, its gland double-screw bolt screws in and compresses and adopts general spanner, misoperation easily takes place cause refrigerant to leak.Valve body and pre-buried valve body do not have axially locating and radial location, so coaxality is poor, and they the two connect with silver soldering, cost is also high.
The purpose of this utility model is the closed stop valve of a kind of improved split-type air conditioner device that proposes at the defective of above-mentioned existence.
Technical solution of the present utility model: structure as shown in Figure 1.Include adapter 1, valve body 2, valve rod 3, little sealing cap 4, valve inside 5, sealing seat 6, seal ring 7, gland double-screw bolt 8, big sealing cap 10, the sealing pair of being made up of sealing seat 6, seal ring 7, gland double-screw bolt 8 is located at the first half of valve body, be the wedge-shaped structure shape, valve rod 3 lower ends in the valve body 2 are single conical surface, and with circular-arc sealing surface, be provided with the lock nut 9 that has screwed locking effect with gland double-screw bolt 8 on the top of valve body, big sealing cap 10 is to be the hexagonal prismoid shape.
Structure is as shown in Figure 2: include valve body 14, valve rod 15, valve inside 16, seal ring 17, go up sealing gasket 18, big sealing cap 20, the sealing pair of being made up of valve body 14, seal ring 17, last sealing gasket 18, gland double-screw bolt 19 is wedge-shaped structure, seal ring 17 wherein is located on the valve body 14, last sealing gasket 18 is located on the seal ring 17, gland double-screw bolt 19 is located on the sealing gasket 18, valve seat 13 welds with the bottom of valve body, valve rod 15 is down-mounting type structures, and valve C end shaft axis and B end shaft axis be not on same straight line.
Accompanying drawing 1 is first kind of structural representation of the present utility model.
Accompanying drawing 2 is second kind of structural representation of the present utility model.
Further describe its technical solution below in conjunction with accompanying drawing:
Narrate according to Fig. 1: copper tube 1 is fixed on to have an end and seals the inner chamber that an end opens and connect on the valve body 2 and with it, the little sealing cap 4 and the connecting head of band valve inside 5 also are housed on the valve body, connecting head and valve body are connected as a single entity, seal ring 7 is housed on the valve rod 3 of keying valve port and compresses double-screw bolt 8, the lower end of valve rod is that single conical surface band circular arc and sealing seat 6 form soft seal, improves sealability.Reach not have and leak, sealing seat 6 and seal ring 7, compress the sealing pair that double-screw bolt 8 forms and be the wedge-shaped structure shape, it can make the axial force that compresses the double-screw bolt screw-in less, but the radial force that seal ring 7 is produced greater than system works pressure, thereby it is reliable to reach sealing, seal ring 7 can remedy the wear extent owing to valve rod 3 upper and lower motions, the working life of guaranteeing valve in addition.Lock nut 9 is and compresses double-screw bolt and screwed locking effect.The upper end that compresses double-screw bolt is an inner hexagonal hole, can only could realize rotation with special-purpose inner hexagon spanner when this just requires to use, and guarantees the safety reliability of using.The upper end of valve rod 3 also is an inner hexagonal hole, and the C of this valve end is realized sealing (the special-purpose valve inside of anti-fluorine) by valve inside 5, increases hard together sealing in addition, promptly forms line by the male cone (strobilus masculinus) of C end and step shoulder blade in the big sealing cap 10 and contacts firmly and seal.The 11st, union nut.
Narrate according to Fig. 2: the copper tube 12 that is fixed on the valve body 14 and connects with its inner chamber, valve inside and little sealing cap end 16 are housed on the valve body, connecting head, the 21st, union nut, the valve rod 15 that opens and closes valve port is a biconical surface structure, be provided with seal ring 17 between valve rod 15 upper ends and valve body, last sealing gasket 18, seal ring 17 and last sealing gasket 18 are combined into sealing, valve body 14, seal ring 17, last sealing gasket 18, gland double-screw bolt 19 is formed sealing pair, sealing pair is the wedge shape structure, and its same available less axial force obtains bigger radial force, guarantees sealing reliability, valve seat cover 13 is to be connected with welding procedure with valve body 14, valve rod 15 is the down-mounting type structure, and is safe in utilization, reliable, the C end shaft axis of valve and B end shaft axis be not on same straight line, the sealing of C end is the hard sealing that increases again on Fig. 1 structure when rotating to the limes superiors position by valve rod 15 together, and C end and upper end form multiple-sealedly like this, can keep nothing leakage under the long-term work pressure.Gland double-screw bolt 19 and big sealing cap 20 and the gland double-screw bolt 8 of Fig. 1 and sealing cap 10 structures, function are identical greatly.
The utility model compared with prior art has following features: seal approach rationally, good sealing effect, uses safely, reliable, easy to operate, in the service life of prolongation air-conditioner, can really reach no leak condition.
